Marty Schoch 5aa9e95468 major refactor of index/search API
index id's are now opaque (until finally returned to top-level user)
 - the TermFieldDoc's returned by TermFieldReader no longer contain doc id
 - instead they return an opaque IndexInternalID
 - items returned are still in the "natural index order"
 - but that is no longer guaranteed to be "doc id order"
 - correct behavior requires that they all follow the same order
 - but not any particular order

 - new API FinalizeDocID which converts index internal ID's to public string ID

 - APIs used internally which previously took doc id now take IndexInternalID
     - that is DocumentFieldTerms() and DocumentFieldTermsForFields()
 - however, APIs that are used externally do not reflect this change
     - that is Document()

 - DocumentIDReader follows the same changes, but this is less obvious
     - behavior clarified, used to iterate doc ids, BUT NOT in doc id order
     - method STILL available to iterate doc ids in range
     - but again, you won't get them in any meaningful order
     - new method to iterate actual doc ids from list of possible ids
         - this was introduced to make the DocIDSearcher continue working

searchers now work with the new opaque index internal doc ids
 - they return new DocumentMatchInternal (which does not have string ID)
scorerers also work with these opaque index internal doc ids
 - they return DocumentMatchInternal (which does not have string ID)
collectors now also perform a final step of converting the final result
 - they STILL return traditional DocumentMatch (with string ID)
 - but they now also require an IndexReader (so that they can do the conversion)
